Red light therapy, a treatment that utilizes light emitting diodes (LEDs) to stimulate collagen production and reduce inflammation in the skin, has gained popularity in the skincare industry since its discovery in the late 1980s. Initially noted for its wound healing benefits by NASA scientists, red light therapy is now widely used in medi spas and homes alike. The treatment is noninvasive and does not involve any heat, making it a safe and accessible option for many people. Red light therapy has been found to improve skin texture, reduce wrinkles, treat pattern hair loss and alopecia, and reduce body fat.
Regular use of red light therapy can lead to increased collagen production and density, improved skin texture, and reduced wrinkles over time. The treatment is also effective in reducing inflammation and supporting healthy collagen production and skin elasticity. These benefits make red light therapy a popular choice for treating a variety of skin concerns, including scarring, fine lines, and acne. Additionally, red light therapy has been found to have healing benefits, such as reducing pain and soreness and promoting healing of deeper tissues.
The frequency and duration of red light exposure depend on the type of device used. In-office red light devices are more powerful than at-home devices, which are recommended for daily or 3-4 times a week use for at least 6 weeks to see results. Skin-firming results may require up to three months of regular red light therapy. While improvements in signs of aging and collagen boosting may take a few months to become noticeable, red light therapy can quickly calm inflammation in a single 10-minute session.
Overall, red light therapy is considered a safe and effective treatment for all skin types. However, there are a few precautions to take, such as closing your eyes during the treatment to avoid potential eye damage from the bright light. It is important to follow the recommended guidelines for frequency and duration of red light therapy to ensure safe and effective results. With its proven benefits for skin rejuvenation, healing, and pain relief, red light therapy continues to be a popular choice for individuals seeking noninvasive skincare treatments.
